STEAM-ENGINE.

SPECIFICATION forming part of Letters Patent No. 8,0=3, dated Novemberf7, 1893.'.

Application tied May 18, 139s.

l ratus for ferry-boats.

The main object of'the invention is to pro- Vide improved means wherebya ferry, or

yother boat can be stopped electrically from a remote point, such as theWheel house.

The invention consists in an apparatus for effecting the obj ect abovementioned, as hereinafter described and set forth in the claims.

In the drawings Figure l is a front view, partly in section, of thepreferred form of apparatus, and Fig. 2 is a view partly in section atright angles to Fig. l, certain parts, however, being omitted.

According to my invention I provide means whereby the valves controllingadmission of steam to the cylinder may be mechanically disconnected fromthe rods or devices, driven by the engine, which normally reciprocatethe valves. The disengaging device is operated by a suitable Huid motorand is controlled electrically from any desired point.

Referring to the drawings@ indicates the tappet shaft of a ferry-boat orsimilar engine, having bearings b, tappets c, and arms d, thelatterbeing adapted, by means of crossbars c carried thereby, to engage withthe hooked levers f, g, of which there maybe four, two on each side ofthe apparatus, and which are reciprocatedby eccentrics on the engineshaft (not shown) in the usual manner. It will be understood that whenthe two levers f engage the arms d the engine will be driven in onedirection, and when the levers g engage said arms the engine will bedriven in' the opposite direction.

.h, Fig. 2, is one of the arms on which the tappets c operate, and whichis secured to the rod i.

' 1l is one of the cut-off valve rods, or stems, arranged in anyWell-known or suitable manner.

Below each pair of rods f g is placed a fluid motor, such as cylinder j,from which extends a piston rod la, carrying at its upper end a rollerZsufficiently long to pass under bot-h serial No. 474,648. (No model.)

rodsf g, as clearly shown in Fig. 1. These cylinders are connected,below their pistons, by a pipe 'm to which a steam inlet pipe, fn, isconnected. In the inlet pipe n is interposed an electrically controlledvalveV,Which may be constructed, for example, as described in my PatentNo. 443,789, dated December 30, 1890.

M is a magnet for operating the valve, and o is a circuit leadingtherefrom to a distant point, such as the wheel house, at which is acircuit closer p. In pipe n is also a three- Way valve q, the passagesin which are indicated in dotted lines.

fr is an exhaust pipe connected to the motor and to any suitable suctiondevice such as a vacuum pump.

-s is a rack secured to the valve and engaging withY rack t, which isnormally held up by a spring, but which can be readily pushed down.

In case of emergency, or whenever the man in the wheel-house, orat thedistant point at which circuit closer p is located, desires to quicklystop the engine, he closes circuit o, opening valve V, thus admittingsteam to the cylinders j, raising their pistons, and through rollersZraising rods f out of engagement with rods t', which, as beforedescribed, are supported in the ends of arms d.

The mechanical disconnection between the valve-rod and its operatingdevices-the eccentric rods-by means controlled from the distant point,is an important feature of my invention. When it is desired to re-setthe pistons the engineer may put his foot on the top of rack t, andpress it down,thereby turning the three-Way valve q, connecting pipe mwith the exhaust pipe r; this lowers the pis.
